Patent GB-853323-A (GB)
Title: Process for the separation of nickel from solutions containing cobalt and nickel salts
IPC: C22B23/00
Filed: 1958-04-28
Abstract: Nickel is separated from an aqueous solution containing a mixture of cobalt and nickel salts by first precipitating the nickel by adding a metal more electronegative than nickel, for example iron, and also one or more metalloidic compounds formed between sulphur, selenium or tellurium on the one hand, and antimony or arsenic on the other.  The separated nickel is then redissolved and the metalloidic compounds regenerated for further use.  Copper may also be added in the first stage of the <PICT:0853323/III/1> process, either as a soluble salt, the amount of copper added being 0.3-2% by weight of the nickel, or as the sulphide, the copper being 10-25% by weight of the nickel. The first stage may be carried out at 50-100 DEG C. and at a pH of approximately 2.5. Suitable metalloidic compounds include arsenic and antimony sulphides, which may be naturally occurring, such as realgars, orpiments, and stibnites and may be employed in an amount 1-2 times by weight of the nickel present in the solution.  Between 1 and 5 times the theoretically required amount of metal more electronegative than nickel may be employed, preferably between 1.1 and 1.3 times, and is preferably in a finely divided state. In an example, a solution of nickel and cobalt sulphate or chloride is heated to above 50 DEG C. with agitation, and copper is added, either as a soluble salt or as the sulphide, which may be added with the metalloidic compound.  Arsenic trisulphide and iron are then added, preferably simultaneously, and the pH is maintained at about 2.5 by acid addition, for example hydrochloric acid.  The suspended solids are then removed and washed.  The cobalt-containing mother liquor remaining is practically free of nickel and copper.  The solids are then treated to regenerate the arsenic trisulphide, for example by suspending in water and passing in chlorine until the nickel is substantially completely dissolved, removing the residue, acidifying and adding a sulphide, for example iron sulphide or preferably hydrogen sulphide, to precipitate arsenic and copper sulphides.  This precipitate may be freed of copper by dissolving the arsenic sulphide in sodium sulphide solution and acidifying to reprecipitate.  The filtrate obtained after the arsenic and copper sulphides have been precipitated is treated to eliminate cobalt and iron by oxidising with chlorine and precipitating ferric hydroxide by adding calcium carbonate to a pH of 3.0-3.5, and precipitating cobalt hydroxide, contaminated with a little nickel which may be recycled to the first stage of the process, by the simultaneous action of chlorine and sodium hydroxide as in Specification 795,410.  The cobalt-containing mother liquor obtained after removing the suspended solids in the initial stage of the process may be freed from iron by precipitation as the hydroxide as indicated above. The accompanying flow sheets illustrates the process of the invention.

Vulcanizing-chambers.-In vulcanizing rubber articles by heating them on mandrels in water under pressure, as described in Specification 276,430, the heat contained in the water is used for a succeeding vulcanization. The apparatus comprises a pair of vulcanizing chambers A, B or a vulcanizing-chamber A and a storage chamber C, means being provided for transferring the heating water from one chamber to another at substantially vulcanizing temperature and for supplying additional heat to replace any loss involved in transit. The water charging system comprises a pump L communicating by means of pipes 46, 28 with a pipe D connected at each end to inlet pipes 22, 22<1> in the bottom of the chambers A, B and joined to upright pipes E, E' leading to spray pipes F, F' situated at the top of the chambers A, B. The flow of water in these pipes is controlled by valves 7, 8, 10, 11, 12, 12<1>. The water is transferred from the chamber A to the chamber B by increasing the air or steam pressure above the water in the chamber A and decreasing the pressure in the chamber B, pipes C supplying air under high and low pressure being connected through valved pipes 37, 37<1> to the chambers and through pipes 36, 36' controlled by valves 14, 19, 20 to an air vent pipe 17. Steam for heating the water in the chamber is introduced from a supply pipe H through valved pipes 15, 15<1> to spray pipes 22, 22<1> and F, F<1>. Cold water for cooling the cured articles may be introduced through a pipe 42 communicating with the pipes E, E<1> by means of valved pipes 43, 43<1>. The water used for vulcanization if not immediately required may be transferred to a storage chamber C by a similar system of pipes and valves. Surplus water found by the condensation of the steam and by the drainage of the articles is led off to a storage tank O from which it is pumped again into the system as required.

Title: Improvements in or relating to string, twine or the like and the use thereof as material (e.g. in the manufacture of boots or shoes) for fastening, plugging or resistingwear
IPC: B31C3/00
Filed: 1926-06-02
Abstract: 278,404. British United Shoe Machinery Co., Ltd., (United Shoe Machinery Corporation). June 2, 1926. Yarns and threads.-Relates to string or twine made of fibrous material and having such uniformity of cross section and stiffness as renders it suitable for use as pegging material in driving pegs into work in shoe making or repairing. In forming such a string, &c. from flat paper strip the twisting is preferably effected in two stages, the strip being impregnated with the sizing before the first twisting and again sized after the second twisting to obtain on the finished string a hardened surface coating of sizing. According to the preferred method the paper strip 10 is fed beneath a roller 14 within a trough 12 of sizing to a die 20, the strip being guided to the die by a spindle 18 coaxial with the die and about which, when a new strip is being inserted, it is curled manually. From the die 20 the strip passes to a spool 26 which is frictionally supported upon a plate 28 which is supported by and rotates with and relatively to a base member 29 which is driven in any suitable manner, the strip being led over a pulley 40, around capstans 38 and about a guide 46 which is reciprocated to lay the strip evenly upon the spool 26. The gearing driving the capstans 38 is preferably arranged to give the strip a twist of about thirty turns to the foot. From the spool 26 the twisted strip is passed through a second twisting mechanism similar to that already described, but preferably having gearing such as will give a supplemental twist of from three to five or six turns per foot, the doubly twisted strip passing therefrom to a drying drum heated by a steam coil, and to a second die similar to die 20 and wherein it is compressed, the compressed product being wound on a reel 88. From the reel 88 the strip is led through the second sizing trough 90 wherein it is coated, surplus sizing being removed by a rubber stripper 94, and the coated strip or string is finally passed through a steam-heated chamber 96 above a baffle plate 100 and wound upon a spool 102. Pegs cut from string formed in this manner may be used as driven fastenings in the manufacture of boots, &c. as described in Specification 253,117, [Class 17 (ii), Boots and shoes, Construction of].
